INHALER.

SPECIFICATION forming part of Letters Patent No. 429,321, dated June 3, 1890. Application filed January 13,1890- Serial No. 336M305. (No model.)

invented certain new and useful Improve ments in Inhalers; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon,which form a part of this specification.

Our improvement relates to a special construction whereby the medicated air (preferably heated or moderatelywarmed) may at will be drawn downward through the mouth-piece into the throat, chest, and lungs, and may also by the action of the respiratory organs be forced upward with the return breath through the nasal passages into the head, the aim being to convey the medicated air to every part of the throat, lungs, and head that can possibly be reached by it. Instead of having only a single tube for insertion in one of the nostrils, or a single main tube having two twin ,chamber common to both, but it has also another or third branch tube communicating with the same chamber, and projecting laterally from it and designed to be placed in the mouth, while the twin tubes are insertible in the nostrils; and my improvement consists in this novel construction, and also in certain details incident thereto, as will presently more fully appear.

In the drawings, Figure 1 illustrates an inhaler embodying my invention; Fig. 2,-a longitudinal section of the same in the line w as of Fig. 1; Fig. 3, a cross-section in the line y 3 of Fig. 1, and Fig. 4 a detail showing the nose-piece made telescopic.

A is the main portion of the tube of the inhaler; b 1), its twin nostril-tubes connecting and communicating therewith, and 0 its chamber, from the end of which these tubes project. D is a lateral or mouth tube, also projecting from the side of chamber 0 and communicating therewith. These parts may be all in one, and may be of china, porcelain,

glass, sheet metal, and nickel-plated, or of rubber or of any other suitable material. The twin tubes, as also the tube D, may be short and each fitted with a rubber tube, and these latter fitted with glass or metallic ends. The main part A serves as a handle, and it may also serve as a receptacle for printed directions placed therein or thereon.

At or near the bottom of each of the twin tubes there is inserted and secured a disk E, of finely-perforated metal, and the ends of all the tubes may be closed by means of corks, caps of rubber or of metal, or rubber stoppers, as preferred. Near the top ends of the twin tubes perforated corks F are preferably inserted, leaving a chamber G between the perforated metal disks and the perforated corks. WVithin these chambers may be placed such medicament, solid or liquid, as may be desired, in connection with cotton, the cotton of course being saturated with the liquids or oils.

It will be understood that before using the inhaler the caps over the ends of the tubes are to be removed, to permit the medicated air to pass through them.

In practice the twin tubes should preferably be made substantially cylindrical or straight, or if tapered at all they should be tapered just at or near the ends to facilitate entering the nostrils. They may, however, be. made perfectly straight and have short telescopic taper ends h on them to facilitate the taking out and putting in of the perforated corks, as also the crystals or saturated cotton. 7

The mouth-tube and the nose-tubes both being in communication with the same medicating-chamber c, and each of the nostriltubes also having its own medicating-chamber, it will be seen that when inhaling first through the mouth the medicated air can at will be taken directly into the throat and lungs, and then by the return breath (the mouth remaining closed) be driven up through the nasal passages into the head, thus permeating every accessible part of the throat, chest, lungs, and head. The instrument also at will permits the drawing up of the medicated air first through the nostrils, and thence down into the lungs, and of discharging it either through the mouth or nostrils. It also permits of inhaling this air through the mouth-tube and of exhalingit through the same tube, and thence again through themedicated material in the body of the device, and thence through the material contained in each of the nosetubes, and thence into the nostrils. In short, the inhaling or exhaling, or both, may be through either the nasal tubes or the mouthtube, or through both of them, as desired. The apparatus thus allows the medicated air to make a complete circuit during the inhaling and exhaling for the in-breathing and for the return or out breath.

lVarm or heated medicated air, when entering the lungs, will not irritate the parts affected. Warm air also medieates more rapidly, and will therefore contain more of the medicament than cold air.

An inhaler having twin nose-tubes and also having" a mouth-tube substantially at right angles to them, each and all these tubes having direct communication with one and the same medieating-chamber in the body of the inhaler.

2. The described inhaling and exhalingapparatus as made with the main part A, twin nasal tubes 1) I), and a mouth-tube, and having in the part A a single medicating-cl1a1nber 0, provided with passages in direct communication with the tubular parts I) b and D,and also provided in each of the tubes 1) b with perforated partitions to constitute between them a medieating-chamber in each of these nasal tubes, and also provided with suitable stoppers or covers for the several tubes, all as set forth.
